Overview
ISO 13342:1995 is an international standard developed by the International Organization for Standardization (ISO) that specifies a standardized method for measuring the static thrust of outboard motors on small craft. This method focuses on accurately evaluating both forward and reverse thrust produced by outboard propulsion systems while stationary. The standard plays a critical role in determining the necessity of start-in-gear protection systems for safety compliance, as outlined in ISO 11547.
By providing a consistent procedure for thrust measurement, ISO 13342:1995 ensures manufacturers and regulatory bodies can rely on robust, reproducible data to validate motor performance and safety features.
Key Topics
Applications
ISO 13342:1995 serves multiple practical purposes in the maritime industry, particularly for:
-
Outboard Motor Manufacturers
Ensures consistent, verifiable thrust performance data for product declarations and compliance testing. Helps manufacturers determine if start-in-gear protection devices are necessary to meet safety regulations.
-
Regulatory Agencies
Facilitates a standardized measurement approach enabling reliable safety certification and enforcement of propulsion system standards on small craft.
-
Boat Builders and Designers
Assists in selecting appropriate outboard motors based on verified thrust capabilities, influencing vessel handling and propulsion system integration.
-
Safety and Compliance Testing Facilities
Provides a clear, replicable method for testing thrust that supports compliance with related standards such as ISO 11547 for start-in-gear protection.
Related Standards
-
ISO 11547:1994 - Small craft - Start-in-gear protection
Defines requirements for protective systems preventing accidental engine engagement while in gear. ISO 13342 thrust measurements help determine when this protection must be implemented.
-
IEC Standards for Electrotechnical Equipment
Given ISO’s collaboration with the International Electrotechnical Commission (IEC), related electrical safety and performance standards may complement the mechanical thrust testing specified in ISO 13342.
-
Propulsion System Performance and Safety Standards
Other ISO and industry-specific standards for engine emissions, noise, and vibration assessments are relevant in comprehensive outboard motor evaluations.
